Santa Barbara County fire agencies responded to a 21-acre vegetation fire reported at Highway 101 and Zaca Station Road Thursday afternoon and a separate, 2-acre fire in the area of Cat Canyon and Palmer roads, south of Sisquoc. 

The brush fire along Highway 101 between Los Alamos and Buellton caused freeway closures in the area, according to Caltrans. 

All lanes in both directions were briefly closed and around 1 p.m., authorities were attempting to reopen at least one lane in each direction. 

The blaze at Highway 101 and Zaca Station Road was reported around noon and County Fire officials called in air resources, and at least two tankers and a helicopter responded to the scene, spokesman Mike Eliason said. 

The fire was first reported to be about 5 acres and burned a total of 21.7 acres, Eliason said.

Noozhawk reader Melissa Cohen said she was at the front of a line of cars on Highway 101 when she was asked to stop and turn around due to the vegetation fire burning near the junction with Highway 154.

A separate 2-acre vegetation fire was reported in the area of Cat Canyon and Palmer roads south of Sisquoc, near the spot of Tuesday’s 15-acre fire
